NAME
    BSON::MaxKey - BSON type wrapper for MaxKey

VERSION
    version v1.12.2

SYNOPSIS
        use BSON::Types ':all';

        bson_maxkey();

DESCRIPTION
    This module provides a BSON type wrapper for the special BSON "MaxKey" type. The object returned
    is a singleton.

METHODS
  TO_JSON
    If the "BSON_EXTJSON" option is true, returns a hashref compatible with MongoDB's extended JSON
    <https://github.com/mongodb/specifications/blob/master/source/extended-json.rst> format, which
    represents it as a document as follows:

        {"$maxKey" : 1}

    If the "BSON_EXTJSON" option is false, an error is thrown, as this value can't otherwise be
    represented in JSON.
